Question

我正在使用couchdb4j与couchDB建立连接。当我连接到我的本地数据库时它工作正常，这是代码：

Session LocalSession= new Session("localhost", 5984);

但我正在尝试与此网站建立联系：stockquotetest.cloudant.com但它无法正常工作，有人能发现问题吗？

Session NewSession = new Session("stockquotetest.cloudant.com/", 5984, "user", "pass");

我收到此错误：INFO：选择了基本身份验证方案

我也得到了这个

当我运行这行代码时：

        Session NewSession = new Session("https://user:pass@stockquotetest.cloudant.com/", 80, true);

Answer 1

我重现了这个并在我开始工作之前遇到了另一个问题。首先，6-parameter constructor for Session就是您所追求的目标：

public Session(String host, int port, String user, String pass, boolean usesAuth, boolean secure) {

在上面给出的示例中，这将起作用：

new Session("stockquotetest.cloudant.com", 443, "user", "pass", true, true);

这是因为如果您未将secure设为true，则为URL will not be constructed with https。

在此工作之后，下一个错误是Database类assuming that update_seq is an int。 Cloudant将返回字符串update_seq，而不是整数。我将Database类中的字段，响应解析和getter从int更改为String，以使代码适合我。

Answer 2

尝试这个...确保你起诉coucjdb4j lib for couchdb connection。

会话studentDbSession =新会话（“localhost”，5984）;

数据库studentCouchDb = studentDbSession.getDatabase（“database_name”）;

希望这会对你有所帮助。
